Hi All,

I have create a simple RESTful service but when I tried to return json I have 
this error:

    java.lang.IllegalStateException: Invalid JSON namespace

Looking at TomEE+ 1.7.1 I saw behind jax-rs implementation there is Apache CXF 
2.6.4, so I tried to configure property ignoreNamespaces = true.

Unfortunately, I haven't found any documentation on TomEE, and looking at 
Apache CXF documentation if I want set ignoreNamespaces = true I should set it 
into `beans.xml`

    <property name="ignoreNamespaces" value="true"/>

Writing something like:

    <jaxrs:server>
      <jaxrs:providers>
        <ref bean="jsonProvider"/>
      </jaxrs:providers>
    </jaxrs:server>
    <bean id="jsonProvider" 
class="org.apache.cxf.jaxrs.provider.json.JSONProvider">
       <property name="ignoreNamespaces" value="true"/>
       <property name="namespaceMap" ref="jsonNamespaceMap"/>
    </bean>

But in this case I got a different error during the TomEE boot:

`Caused by: javax.xml.bind.UnmarshalException: unexpected element 
(uri:"http://java.sun.com/xml/ns/javaee";, local:"server"). Expected elements 
are 
<{http://java.sun.com/xml/ns/javaee}decorators>,<{http://java.sun.com/xml/ns/javaee}interceptors>,<{http://java.sun.com/xml/ns/javaee}alternatives>`

What do you think, should I continue configure cfx or try to use a different 
implementation (Jersey)?
